1715-TASOF8 Redundant I/O 8-Channel Analog Output Module | Allen Bradley

Product Overview

The Allen Bradley 1715-TASOF8 functions as a high-integrity, 8-channel analog output module specifically designed for the 1715 Redundant I/O platform. This module provides critical control signals (0 to 24 mA) to field devices such as valve positioners and actuators in applications requiring non-stop operation. It supports fault-tolerant configurations, allowing the system to maintain control even during hardware transitions. We supply this unit as 100% Brand New and Original, ensuring your safety-instrumented systems and critical control loops operate with OEM-certified precision.

Technical Specifications

The 1715-TASOF8 operates with the following electrical and physical parameters:

Engineering Advantages

The 1715-TASOF8 resolves complex availability and signal interference challenges in heavy industry:

• High-Availability Architecture: This module integrates into the 1715 redundant bus, allowing for "Hot Swap" replacements without dropping the field signal. This eliminates downtime in continuous process industries like oil and gas or chemical refining.

• Extended Output Range: The 0 to 24 mA capability provides additional headroom beyond the standard 4-20 mA range. This allows the controller to drive signals into over-range conditions for diagnostic purposes or specialized valve calibration.

• Optimized Thermal Management: Low power dissipation (only 0.64 W per field loop) prevents heat buildup in high-density cabinets. This design maintains module longevity and prevents thermal-induced signal drift in high-ambient temperature environments.

• Enhanced EMI Shielding: The module requires shielded signal ports (Wiring Category 2), which effectively isolates sensitive analog control signals from the electromagnetic noise generated by nearby variable frequency drives and high-voltage motors.

FAQs

• Does this module support redundant configurations?

  Yes. The 1715-TASOF8 is specifically built for the 1715 redundant I/O system. When installed in pairs on a redundant adapter base, it ensures that your analog output signal continues uninterrupted if one module fails.

• What type of wire should I use for installation?

  Always use shielded copper wire rated for at least 85 °C (185°F). For optimal signal integrity and compliance with the module’s wiring category, utilize 22 to 16 AWG solid or stranded shielded cable.

• Is there isolation between the individual output channels?

  The 1715-TASOF8 provides 50V continuous isolation between the I/O ports and the backplane. However, no isolation exists between individual I/O ports on the same module; therefore, you must ensure your field devices share a compatible common reference.

• How do I confirm the "Brand New" status of this unit?

  We deliver every 1715-TASOF8 in its original factory packaging. Each unit features the authentic Allen Bradley serial number and intact factory seals, ensuring the hardware has never been previously installed or refurbished.
